Summary

Volumes of red cells and plasma were measured in organs of normal and “hypersplenic” rats by means of59Fe-labelled erythrocytes and131I-labelled human serum albumin respectively. The “hypersplenism” was induced by a long-term intraperitoneal application of methylcellulose. Blood volumes in the spleen and myocard of normal rats formed roughly one-fifth, in the kidneys, lungs and liver about one-fourth to one-third of the organ weight. The absolute volume of red cells, plasma and blood in the spleen of “hypersplenic” rats was higher than in controls. When expressing these values as a per cent from the total blood volumes, 7.5times more red cells and 5times more plasma were found in “hypersplenic” rats compared with normal animals. These results speak for an existing splenic pool of red cells. The changes of blood volumes in other organs (liver, kidneys, lungs and myocard) were far more discrete.

The values of venous and organ blood hematocrits were given.

Zusammenfassung

In den Organen normaler und “hypersplenischer” Ratten wurde das Erythrozytenvolumen mit Hilfe der59Fe-markierten Erythrozyten und das Plasmavolumen mit Hilfe des131I-markierten Serumalbumins untersucht. Der “Hypersplenismus” war durch langfristiges intraperitoneales Verabreichen von Methylzellulose induziert worden. Bei normalen Ratten betrug das Blutvolumen in Milz und Myokard ungefähr ein Fünftel, in Nieren, Lungen und in Leber ein Viertel bis ein Drittel des Organgewichts. Das absolute Volumen der Erythrozyten, des Plasmas und des Blutes in der Milz war bei den “hypersplenischen” Ratten größer als bei den normalen Kontrolltieren. Wenn diese Werte als Prozentsatz der Gesamtblutvolumina ausgedrückt werden, findet man in der Milz 7,5mal größeres Erythrozytenvolumen und 5mal größeres Plasmavolumen bei den “hypersplenischen” als bei den normalen Tieren. Diese Ergebnisse sprechen für die Existenz eines Erythrozyten-Pools in der Milz. In den übrigen untersuchten Organen (Leber, Nieren und Myokard) waren die Änderungen der Blutvolumina nicht markant.

Die Hämatokritwerte des Venen- und Organblutes wurden bestimmt.
